My 10D with both neck strap and old Herritage (black) hand strap that I've had for 3 years or so. The bottom part of the strap near the base plate is a little worn from use. Hardly used the 10D with both straps, but put the strap on when I was shooting with both cameras. I leave the little metal tab (for the neck strap) on just in case.
Here is my 7D with the Chocolate Seduction Limited Edition hand strap (and neck strap not shown in the picture) that was given to me for free by Canon Korea when I bought the 7D. I had already bought another Herringbone black hand strap when I first ordered accessories for my new 7D and was surprised when Canon Korea gave me the brown one.

The brown is quite dark so it does not stand out that much.
